Novel steel plate lifting frame capable of accurately positioning lifting hook

Abstract

The invention discloses a novel steel plate lifting frame capable of accurately positioning a lifting hook. The novel steel plate lifting frame comprises two frames which are connected together and can be dislocated by an angle through relative rotation. The frame is provided with a lifting hook system capable of achieving automatic lifting and grabbing, a steel plate alignment mechanism, a heightlimiting mechanism adjusting the steel plate number, a lifting rope and a connecting plate of the lifting rope. A body frame is composed of a cross beam, a longitudinal beam, a slanting beam and a connecting beam. The lifting hook system and the steel plate alignment mechanism are arranged at the upper end of the cross beam. The lifting hook system is provided with the lifting hook, an oil cylinder, a synchronous telescopic rod and a synchronous connecting rod mechanism. The steel plate alignment mechanism is provided with an extruding plate, an oil cylinder, a synchronous telescopic rod anda synchronous connecting rod mechanism. A frame hinge mechanism is arranged in the center of the cross beam on the inner sides of the two frames. By means of the novel steel plate lifting frame capable of accurately positioning the lifting hook, it can be ensured that the lifting hook grabbing point can still be accurately positioned in the situation that steel plate stacking is not flat and neat, stable lifting of steel plates with the set number is achieved, the adaptability is high, and operation is simple.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to a novel steel plate hanger capable of accurately positioning a hook. Background technique [0002] The steel plate is flat steel. During the production or use of the steel plate, it needs to be transported in batches many times. Due to the large volume and huge weight of the steel plate in batches, it cannot be transported by ordinary transport tools. The existing steel plate special-purpose spreader has a simple structure, and lifts by driving four hooks installed on the overall frame; before lifting, manual assistance is usually required to position the lifter's hooks in the gaps between the steel plates to be lifted , and then clamped by the driving mechanism of the spreader, and then lifted for transportation. Due to the misalignment of the steel plates often occurs when the steel plates are stacked, it is difficult to ensure that the stacking is neat, and this...

AI Technical Summary

Problems solved by technology

Due to the misalignment of the steel plates often occurs when the steel plates are stacked, it is difficult to ensure that the stacking is neat, and this will cause the hook tip to be affected by the upper and lower plates when hoisting, and it is difficult to enter the gap between the plates, so that it cannot be carried out. Hoisting; and when the steel plates are stacked, they will be affected by factors such as the flatness of the ground, the consistency of the pads, and the placement method, and flexible bending will occur, resulting in uneven stacking, resulting in the position of the four lifting points corresponding to the hook of the spreader. On the plane, because of the structure characteristics of the integral frame type hoist, the four hooks are determined to be on the same plane, so when using the hoist, there is often a problem that only three hooks can be accurately positioned, and the other hook has a height deviation As a result, the hook cannot be accurately hooked into the gap between the steel plates, and the problem cannot be solved by adjusting the spreader. The fourth lifting point of the steel plate can only be pried open by manual assistance for the hook to be wedged in, which brings great impact to the use of the equipment. inconvenience and safety hazard
